These are so cute, fun, and useful! I love my set so much. I made custom popsicle flavors with my own juices and fresh fruits at first and loved it. You can make the most amazing strawberry lemonade pops in these. I add fresh strawberries and it makes them a huge hit with everyone! I also have used these to store candies and nuts on the go. I love buying "to-go" packs for convenience, but they can be really quite expensive and results in far too much extra packaging to throw away. I prefer this economical option to snack storage! Mine sealed really well and never leaked when used in freezing or transport.
